    Abstract: An interconnection scheme between a filter cartridge and its corresponding manifold whereby a magnetic shear force is introduced to remove a blocking mechanism that would otherwise prohibit attachment. The magnetic shear force may also be employed to activate or deactivate a switch or valve, or engage or disengage an engagement mechanism relative to other components upon interconnection. The magnetic shear force is generated by complementary correlated magnet structures moved into close proximity to one another. The interconnection scheme may be a linear or rotational attachment of the filter cartridge with respect to the manifold. A valve assembly utilizing magnetic shear force may be employed to activate a bypass action between a manifold ingress port and egress port, thereby allowing water to flow when a filter cartridge is removed from the manifold and directing water to the filter cartridge when the valve assembly is activated.

    Abstract: A filtration system interconnection structure having manifold with a rotatable manifold magnet of correlated magnets, a shroud with alignment tracks, an actuating valve for water ingress, and a filter cartridge having a rotatable filter magnet of correlated magnets, where the manifold magnet and the filter magnet are in magnetic communication with one another when the filter cartridge is inserted with the shroud, and are at least partially rotatably compatible, where the manifold magnet rotates with the filter magnet until the manifold magnet experiences a rotational stop beyond a predetermined rotation of the filter magnet, thus allowing the filter magnet to shift polarity with respect to the manifold magnet and present a repulsion force for removal of the filter cartridge from the shroud.

    Abstract: A gravity-fed filtration system interconnection structure comprising a reservoir for receiving ingress fluid, the reservoir having a bottom surface with a recess for receiving a filter cartridge body, and an opening for filtered fluid egress to a second, dispensing reservoir. A carrier or shuttle having a magnet disposed within or connected to the carrier is adjacent to the reservoir recess and connected to a sluice gate valve which normally blocks the opening to the second reservoir. The interconnection structure further includes a filter cartridge having a housing body, and a filter magnet disposed within or fixedly connected to the housing body. The carrier is normally biased in a first position, such as a closed position, and is moveable between the first position and a second (open) position, and the filter magnet and the carrier magnet are interconnected via magnetic communication upon insertion of the filter cartridge into the reservoir recess, such that upon relative movement of the filter magnet and carrier magnet into an alignment position, the carrier moves to the second position as a result of the magnetic communication. In one embodiment, the carrier translates axially upwards within a channel in the reservoir recess wall as a result of the magnet communication. In another embodiment, the carrier shifts radially in a direction perpendicular to the longitudinal axis of the filter cartridge body. In still another embodiment, the carrier rotates about the longitudinal axis of the filter cartridge. The filter magnet polarity transitions are aligned with the carrier magnet polarity transitions such that a shear force or rotational force is generated between the magnets when the filter cartridge is inserted within the reservoir recess, causing the carrier to move from the first position to the second position.

    Abstract: A filtration system interconnection structure having a filter manifold and a filter cartridge in magnetic communication with one another, such that a latching mechanism of the manifold secures the filter cartridge within a manifold sump when the filter cartridge is inserted therein. The magnetic communication is formed between two complementary coded polymagnets capable of producing a magnetic shear force when in close proximity to one another. The magnetic shear force removes a latch blocking structure from interfering with the latch, allowing the latch to secure the filter cartridge. Movement of the latch blocking structure coded polymagnet relative to the filter cartridge coded polymagnet may be perpendicular or parallel with respect to each other such that a shear force is generated therebetween, allowing for actuation of the latch blocking mechanism against a biasing force, and allowing the latch to move radially inwards against a separate biasing force.

    Abstract: A filtration system interconnection structure includes a filter manifold and a filter cartridge in magnetic communication produced by two complementary correlated magnets capable of generating a magnetic force when in close proximity to one another. The filter magnet polarity transitions are aligned with the manifold magnet polarity transitions such that a repulsion force is generated between the magnets when the filter cartridge is inserted within the manifold sump. The magnetic repulsion force may be used to move a blocking mechanism or actuate a latch structure in the manifold to secure the filter cartridge within the manifold sump upon insertion, or to provide non-contacting actuation of a downstream valve so as to permit or prevent the flow of fluid. Utilizing correlated magnetism in a filter interconnect further provides enhanced authentication and/or anti-counterfeiting means to ensure that only authorized or OEM filter cartridges can be installed.
